I've never been a big avatar sort of guy, but thinking about what I'd put if I was to use one in this context would probably be He-Man, or another Masters Of The Universe character. Probably my most rabbid, long running interest as a child (apart from computers), starting in 81 when I was 5 (ironically the same year I got my 1st computer, a tandy trs80 coco1) until about 11. Over that time I amassed quite a collection. About 40 figurines, 2 castles, about a dozen vehicles, and a shedload of comics. Even as I got older I still kept them. Packed up and out of the way, but I didnt want to get rid of them. Unfortunately some mongrel sold them on me in secret on the side. Being that by that age they were in storage and out of everyday eyeshot I didnt learn this until almost a month later. Bit of a shame, as by now collectively they'd probably be worth a few $.
